Evidence:

"One of the features of human problem solving is the tendency we have to connect any two events occurring simultaneously (or nearly simultaneously) as arising from the same cause (Tversky & Kahneman, 1974). Further, it may be that the primary cause in many cases will not be the first failure to be communicated. The crew must, therefore, either recognize the pattern of failing secondary systems or sift through the warning information to seek the primary cause. In terms of presentation of warning information, this poses a difficult problem to address; the first failure to be brought to the crew’s attention is likely to be the one they attempt to deal with initially. This issue was addressed via the following two statements:
1. There is a clear rationale for the classification of warning conditions into
categories (e.g., warning, caution, and advisory)....
Analyses of the responses to these statements do not follow an obvious pattern. For the first statement, the mean response was 2.54 (SD = 1.98), with crew from the Type A fleets showing greater disagreement with this statement about a clear rationale." (page 181)
